b1bf9ef5ae Break fold's circular reference during unwinding 
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.

43b219dbec Work around an apparent compiler bug to make my patch run 
Without this, it would fail when optimization is turned on. The result of
the Load(bcx, llclosure) call would end up in llenv in a corrupted form.

575aae407b Saner approach to lvalues and callable values in trans 
LValues no longer carry information about generics and objs, instead
there's an extended form of lvalue, lval_maybe_callee, only used by
call and bind, which holds this info.

This makes it possible to take the value of a method and get a working
closure, and will (with some more work) allow us to call statically
known functions without loading from their pair.

f8a35234ad Remove autoderef for calls

d7587c1eda Change convention for specifying referenced argument 
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

0b34e0e60b Introduce new semicolon rules 
- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).

be5537e95f Be more strict about what constitutes a block expression 
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:

    { if foo { ret 1; } else { ret 10; } }

b5f9053423 Add a constraint to trans::type_of 
trans::type_of now has a constraint saying that its type argument

in type_of. Yay!

I note that this change decreased translation time for stage2/rustc
from 16.1 s to 14.0 s. I also think many of the remaining checks
could be eliminated with some mildly clever use of constrained types
and further preconditions. Future work!
